Laser-Polarized Liquid Xenon
Abstract
Gaseous and solid laser-polarized ^129Xe have already been extensively studied. Now we extend the investigations to the liquid phase. We measured the relaxation rate of the ^129Xe polarization in liquid Xe as a function of magnetic field, temperature, and container surface. Lifetimes in excess of 30 minutes were observed. The relaxation rates displayed a mild dependence on temperature and surface environment, and a very mild dependence on field. Potential applications of laser-polarized liquid Xe include transportation of large quantities of hyperpolarized ^129Xe (as needed for medical imaging work) and cross-relaxation to other nuclear species dissolved in the liquid.
